earth to galaxy distance

earth to galaxy distance

The Hydra Supercluster is about 100 million light years long, and the galaxy clusters within it range from about 105 to 160 million light years away from us. Its distance is 158, 200 light years to the Earth. Science, this issue p. 565; see also p. 546. “From this, they derived a refined distance of estimate of 7.6 to 8.2 kpc – which works out to about 24,788 to 26,745 light years.” Which is off by a factor of 10. Astronomers nail down distance to the earliest galaxy yet The galaxy EGS-zs8-1, the most distant galaxy yet seen, was discovered in images from the Hubble and Spitzer space telescopes. while the Andromeda galaxy is 2.537 million light years away. Localizing FRBs will help determine their causes and allow them to be used as cosmological probes. Mystery Object Comet Holmes in the Kuiper Belt. In the solar system "A" is the distance from Earth to the Sun, the astronomical unit, 150,000,000 km or 93,000,000 miles. Fast radio bursts (FRBs) are brief radio emissions from distant astronomical sources. You must consider one thing however, there is no way for us to look down upon our own galaxy as we might with the Andromeda galaxy for example. image from www.daviddarling.info This is one representation of what our galaxy may look like. The diameter of this galaxy is 220000 light years. The extremely large redshifts of various quasars suggest that they are moving away from the Earth at tremendous velocities (i.e., approximately 90 percent the speed of light) and thereby constitute some of the most distant objects in the universe. ), provided p is small (which it is for all stars), that the distance D to the near star is given by 206265 AU / p, where AU is the astronomical unit mentioned above (i.e., the distance from the earth to the sun, 150 million km or 93 million miles), and p is the parallax angle measured in seconds of arc. The Andromeda Galaxy located at a distance of 2 million light years away is the nearest major galaxy and is of comparable size to our own galaxy. Remember that, whatever we use to measure these vast distances, it must be very luminous. So one thing, this huge distance wouldn't even show up on this picture. Suppose a certain galaxy is twice as large as an average galaxy. The distance ranking in this list should be seen only as a guess. Just like your fingertip, stars that are closer to us shift positions relative to more-distant stars, which appear fixed. If you look at a cluster of galaxies then you can also improve matters by $\sqrt{n}$ by averaging over the individual galaxy peculiar motions. It's a big flat disk of stars measuring up to 120,000 light years across. The important thing about clusters is that all the stars in the cluster are at (nearly) the same distance from Earth. Andromeda galaxy distance from Earth is 2.5 million light years. A parsec is a unit of distance equal to 3.26 light-years. The Andromeda Galaxy (IPA: / æ n ˈ d r ɒ m ɪ d ə /), also known as Messier 31, M31, or NGC 224 and originally the Andromeda Nebula (see below), is a barred spiral galaxy approximately 2.5 million light-years (770 kiloparsecs) from Earth and the nearest major galaxy to the Milky Way. The closest known galaxy to us is the Canis Major Dwarf Galaxy, at 236,000,000,000,000,000 km (25,000 light years) from the Sun. The Milky Way Galaxy is organized into spiral arms of giant stars that illuminate interstellar gas and dust. distance scale for the Galaxy would lead to better estimates of the ages of globular clusters, Ho, and the age of the Universe. So, if our distance to the LMC is uncertain by 10%, then every single distance to another galaxy will be uncertain by at least 10%. The Earth is a tiny planet on a galaxy known as Milky Way galaxy, which is just one of the many billions of galaxies that form the universe. It takes eight minutes for light to get from the Sun to the Earth, this super long distance. The Kubasik Galaxy does not exist in real life.
